The Spanish striker scored two goals in Liverpool’s 3-2 victory over West Ham over the weekend.
“We knew Fernando would score,” he told the Reds’ official website.
“We all have 100 per cent confidence in him and we trust him always. He is always working hard for the team and he always creates space for the other players for them to score.
“His first goal was unbelievable. His turn was fantastic and he showed his quality.”
